Quantum many-body scars in a Landau level on a thin torus
We study a kinetically constrained pair-hop** model that arises within a Landau level in
the quantum Hall effect. At filling ν= 1/3, the model exactly maps onto the so-called “PXP …

Hydrodynamics in long-range interacting systems with center-of-mass conservation
A Morningstar, N O'Dea, J Richter - Physical Review B, 2023 - APS
In systems with a conserved density, the additional conservation of the center of mass
(dipole moment) has been shown to slow down the associated hydrodynamics. At the same …
